The ZDA 928 MHz ISM Directional Yagi Antenna is a rugged, high-performance solution engineered to deliver reliable long-range communication across the 902–928 MHz ISM band. Designed for demanding outdoor environments, this antenna excels at pulling in weak signals and maintaining stable, low-noise links for industrial wireless networks where consistency and uptime are critical. Offered in four configurations, the lineup delivers 8 to 17 dBi of focused directional gain with selectable horizontal or vertical polarization for system flexibility. Every unit is verified through a strict QC process to ensure a VSWR of ≤ 1.5, minimizing return loss and protecting connected radios. Each model features a 50 Ω N-Female interface, supports up to 200 W input power, and maintains strong front-to-back performance to keep links clean in noisy RF environments. Built from durable aluminum alloy, the antenna is rated for reliable, weatherproof, field-tested operation in industrial deployments.
